RESEARCH: OUTCOMES, VIEWPOINTS & PERSPECTIVES

From 1991 to 1998, a volumetric seven-day recording spore trap (Type Hirst; manufactured by Burkard), located at about 19 m a.g.l. was operated on the exposed flat roof of the Veterinary Faculty of Murcia University (110 m a.s.l., 38º 01` N, 1º 10`W), 4 km NW of Murcia central city. Daily slides were prepared and subsequently examined at our lab following standard methods of the REA (Red Española de Aerobiología).

Aerobiology of Artemisia airborne pollen

Three consecutive pollen seasons of Artemisia occur each year, related to three different species, namely A. campestris, A. herba-alba, and A. barrelieri.

A winter blooming of Artemisia could explain the incidence of subsequent pollinosis. Mathematical analyses showed relationships between daily pollen concentrations of Artemisia in summer-autumn and precipitations that occurred 6-8 weeks before. The cumulative percentage of insolation from 1 March seemed to be related to blooming onsets.
